In this work, we report the obtention of the LDH@Bi2WO6 heterostructure using an easy and low-cost method. The LDH was synthesized through the co-precipitation method with the metallic ratio of Mg2+/Al3+ = 2.0, while the bismuth tungstate nanoplates were prepared using the hydrothermal method. The LDH@Bi2WO6 heterostructure was obtained mixing LDH in water with 20 wt% of Bi2WO6. The LDH, Bi2WO6 and LDH@Bi2WO6 heterostructure were characterized by XRD, FTIR, N2 sorption, SEM, TEM, Raman, and DRS…

Synthesis, characterization and enhanced visible light photocatalytic activity of Bi2WO6/Ni–Al layered double hydroxide composites
Bi2WO6/Ni–Al layered double hydroxide (LDH) composites assembled from Bi2WO6 and Ni–Al LDH composites were prepared by a simple hydrothermal method. The as-prepared composites were characterized by
High Photocatalytic Activity under Visible Light for a New Morphology of Bi2WO6 Microcrystals
In this work, a new morphology was obtained for bismuth tungstate (Bi2WO6-glyc) using a hydrothermal method with the addition of glycerol as a surfactant. In order to compare, the bismuth tungstate
Facile Fabrication of Bi2WO6/Ag2S Heterostructure with Enhanced Visible-Light-Driven Photocatalytic Performances
TLDR
The mechanism of the photocatalytic process was proposed by the active-species-trapping experiments, indicating that the photogenerated holes play a crucial role in the degradation of Rh B under visible light.
A Bi2WO6/Ag2S/ZnS Z-scheme heterojunction photocatalyst with enhanced visible-light photoactivity towards the degradation of multiple dye pollutants
A novel visible-light-driven Z-scheme heterojunction, Bi2WO6/Ag2S/ZnS, was synthesized and its photocatalytic activity was evaluated for the treatment of a binary mixture of dyes, and its
Construction of 3D marigold-like Bi2WO6/Ag2O/CQDs heterostructure with superior visible-light active photocatalytic activity toward tetracycline degradation and selective oxidation
AbstractA novel visible-light-driven photocatalyst Bi2WO6/Ag2O/CQDs (BWO/Ag2O/CQDs), which possesses hierarchical superstructure with marigold-like appearance, was fabricated via a hydrothermal
